Figure 1. Scatterplot of vaginal concentration of IL-1β and serum CRP in pregnant and non-pregnant women.

Figure 1

a. Levels of IL-1β reported in pg/nl. The Y-axis has been transformed to logarithmic scale in order to allow better comparison among groups. A statistically significant difference was noted between groups during the first trimester and the postpartum period (p = 0.008 and p = 0.04, respectively).

b. Serum CRP levels reported in ng/L. A statistically significant difference was noted between groups during the first, second and third trimester (p = 0.005, p < 0.0001 and p = 0.03, respectively).
